I have my 318 working great in my '77 truck, other than the stalling problem. First, let me tell you guys what i got on it.

msd blaster 2 coil

mopar orange box

headers

true duals with h pipe and cherry bombs

super tall filter, two normal frams stacked ontop of each other.

rebuilt carter bbd carb ( i rebuilt it)

when i try womping it, it will almost instantly stop, but if i go slow on the gas, it will go fine, when i have it about mid throttle, and then i stomp on her fast, it will stutter, then will run to full roar (awesome feedback growl with the cherry bombs ) Ive tried adjusting the accelerator pump, didn't really help much

ive tried adjusting the mixture, if i tried putting it more into it, a carb backfire would happen.

with the backfire, im thinking maybe the timing is a little off, especially since i put the orange box and coil on, maybe i need to retard or advance it a few degrees, since the spark is more powerful now.

I'm not familiar with the carb you said you had but it sounds like the accelerator pump jet is blocked or the accel. pump itself (usually a plunger or diaphragm) has a fault of some description. Unless the ignition timing is miles out, that would be more likely to cause either low power right through the rev range (retarded) or pre-ignition (advanced).

Without the engine running, take the filters off and manually move the throttle linkage to full throttle while looking down the carb - there should be two healthy squirts of fuel being pumped into the primary venturis, they should start squirting right off the idle stop.
